UIO memmap of PCi devices not working?

[Joakim Tjernlund]

Having problems to mmap PCI UIO devices and stumbeled over this page:
 http://billfarrow.blogspot.se/2010/09/userspace-access-to-pci-memory.html
it claims some adjustments are needed for UIO mmap over PCI to work.
These are #if 0 ATM and trying to enable them fails build.

Can this be fixed to at least build again ?
The reason for having #if 0 in the first place appears to be old X servers,
is that still true? Can the special casing be removed now?
